Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulating paper processing technology, specifically to a coating device for insulating paper processing. Background Technology
[0002] In the process of insulating paper processing, the coating process is a key step to ensure the performance of insulating paper. Traditional coating equipment has many problems in practical applications, which limits the quality and efficiency of insulating paper processing.
[0003] Traditional coating equipment typically uses simple coating rollers or doctor blades to apply coatings. During the coating process, these devices are prone to uneven coating due to inaccurate coating flow control and uneven contact pressure between the coating roller and the insulating paper. For example, some areas may have excessively thick coating while others have insufficient coating, which affects the insulation performance and appearance quality of the insulating paper. Furthermore, traditional equipment often results in coating dripping or overflowing, leading to waste. This increases production costs and can also contaminate the equipment and working environment, affecting normal operation and maintenance. Therefore, a coating device for insulating paper processing is proposed to address these problems. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a coating device for processing insulating paper, which addresses the shortcomings of the prior art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a coating device for processing insulating paper, including a coating frame, two rotating shafts and one rotating shaft are installed on the inner side of the coating frame, and rubber rollers are fixedly sleeved on the outer wall of the rotating shafts on both sides, and a roller is fixedly sleeved on the outer wall of the rotating shaft in the middle. Insulating paper is wound around the outer wall of the rubber roller and the roller. A paint hopper is installed on the inner wall of the coating frame for storing paint, and a discharge hole is opened on one side of the paint hopper. The bottom of the paint hopper is attached to the top of the insulating paper for coating the top of the insulating paper.
[0006] Preferably, the bottom of the paint tank is provided with an arc-shaped plate, and the top of the arc-shaped plate is fixedly connected with multiple push rods, which move upward and penetrate into the interior of the paint tank. The outer wall of the push rod is fitted with a tension spring, which is used to pull the push rod downward to drive the arc-shaped plate to move downward.
[0007] Preferably, the bottom of the arc-shaped plate is provided with a plurality of bristles, and the bristles are attached to the outer wall of the insulating paper, the bristles being used to evenly apply the coating.
[0008] Preferably, a baffle plate is provided on the left side of the outer wall of the paint tank, and multiple arc-shaped rods are fixedly connected to the baffle plate. The arc-shaped rods movably pass through the paint tank and extend into it. A spring is sleeved on the outer wall of the arc-shaped rods, and the two ends of the spring are connected to the baffle plate and the outer wall of the paint tank, for pushing the baffle plate against the outer wall of the insulating paper and against the roller.
[0009] Preferably, the coating rack has two sliding holes, and an adjusting rod is slidably connected in the sliding holes. A scraper is connected to one side of the adjusting rod, and the scraper is attached to the outer wall of the insulating paper to scrape off the coating on the insulating paper.
[0010] Preferably, a screw is provided in the sliding hole, and the screw thread passes through the coating frame to push the adjusting rod to move, and to push the adjusting rod and the scraper to adhere to the outer wall of the insulating paper.
[0011] The present invention adopts the above technical solution, which can bring the following beneficial effects:
[0012] 1. This coating device for insulating paper processing has brush bristles at the bottom of an arc-shaped plate that adhere to the outer wall of the insulating paper. After the coating flows out from the coating chamber, it is guided to the brush bristles by the arc-shaped plate. Under the pressure of the roller, the brush bristles adhere tightly to the insulating paper, which can evenly coat the coating. This effectively avoids the accumulation of coating on the surface of the insulating paper or uneven coating, ensuring that the coating thickness on the surface of the insulating paper is uniform and improving the coating quality of the insulating paper. At the same time, a tension spring is sleeved on the outer wall of the push rod. Pulling the push rod downward causes the arc-shaped plate to move downward, providing stable downward pressure for the brush bristles. This ensures good contact between the brush bristles and the insulating paper, so that the coating can be evenly distributed on the entire surface of the insulating paper. Even when there are slight unevennesses on the surface of the insulating paper, the uniformity of coating can be guaranteed.
[0013] 2. In this coating device for insulating paper processing, a flow-blocking plate is connected to the coating hopper via an arc-shaped rod and a spring. The spring pushes the flow-blocking plate against the surface of the insulating paper and the roller. The flow-blocking plate can effectively collect the coating dripping from the surface of the insulating paper, avoiding coating waste and preventing coating from dripping onto other parts of the equipment, keeping the equipment clean, improving coating utilization efficiency, and reducing production costs. Furthermore, the bottom of the coating hopper is directly attached to the top of the insulating paper, allowing the coating to flow directly from the coating hopper to the surface of the insulating paper, reducing coating loss during transmission. The discharge hole of the coating hopper ensures smooth coating flow, further improving coating utilization efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-5 One embodiment of this utility model is: a coating device for processing insulating paper, including a coating frame 1, two rotating shafts 4 and one rotating shaft 17 are installed on the inner side of the coating frame 1, and rubber rollers 5 are fixedly sleeved on the outer wall of the rotating shafts 4 on both sides, and a roller 6 is fixedly sleeved on the outer wall of the rotating shaft 17 in the middle. Insulating paper 2 is wrapped around the outer wall of the rubber rollers 5 and the roller 6. A paint tank 3 is installed on the inner wall of the coating frame 1 for storing paint, and a discharge hole is opened on one side of the paint tank 3. The bottom of the paint tank 3 is attached to the top of the insulating paper 2 for coating paint onto the top of the insulating paper 2.
[0022] The bottom of the paint tank 3 is provided with an arc-shaped plate 7, and the top of the arc-shaped plate 7 is fixedly connected with multiple push rods 9, which move upward and penetrate into the interior of the paint tank 3. The outer wall of the push rod 9 is fitted with a tension spring 10, which is used to pull the push rod 9 downward to drive the arc-shaped plate 7 to move downward.
[0023] The bottom of the curved plate 7 is provided with multiple bristles 8, and the bristles 8 are attached to the outer wall of the insulating paper 2. The bristles 8 are used to evenly apply the coating.
[0024] A baffle plate 11 is provided on the left side of the outer wall of the paint tank 3, and multiple arc-shaped rods 12 are fixedly connected to the baffle plate 11. The arc-shaped rods 12 move through the paint tank 3 and extend into it. A spring 13 is sleeved on the outer wall of the arc-shaped rod 12, and the two ends of the spring 13 are connected to the baffle plate 11 and the outer wall of the paint tank 3, which are used to push the baffle plate 11 against the outer wall of the insulating paper 2 and against the roller 6.
[0025] The coating rack 1 has two sliding holes, and an adjusting rod 15 is slidably connected in the sliding holes. A scraper 14 is connected to one side of the adjusting rod 15, and the scraper 14 is attached to the outer wall of the insulating paper 2 to scrape off the coating on the insulating paper 2.
[0026] A screw 16 is provided inside the sliding hole, and the screw 16 is threaded through the coating frame 1. It is used to push the adjusting rod 15 to move and to push the adjusting rod 15 and the scraper 14 to adhere to the outer wall of the insulating paper 2.
[0027] Working principle: When processing insulating paper, it is necessary to apply coating to the surface of the insulating paper. At this time, the insulating paper 2 is wrapped around the outer wall of the rubber roller 5 and the roller 6. At this time, the coating inside the coating tank 3 will flow onto the insulating paper 2 from one side of the coating tank 3. Then, the tension spring 10 pulls the push rod 9 to move downward and pushes the arc plate 7 to move downward, causing the brush bristles 8 to adhere to the insulating paper 2. With the pressure applied by the roller 6, the coating that falls onto the insulating paper 1 can be evenly applied to improve the coating effect. Furthermore, the spring 13 pushes the anti-flow plate 11 to contact the surface of the insulating paper 2 and the surface of the roller 6, thereby collecting the coating and preventing the coating from dripping, thus improving the coating effect.
[0028] Furthermore, the scraper 14 will adhere to the surface of the insulating paper 2, thereby scraping off the excess coating adhering to the surface of the insulating paper 2 and preventing the coating from accumulating on the surface of the insulating paper 2. At the same time, by rotating the screw 16, the adjusting rod 15 can be pushed to move in the sliding hole, thereby pushing the scraper 14 to move and come into contact with the surface of the insulating paper 2, so as to remove the excess coating on the surface of the insulating paper 2 and improve the coating effect of the insulating paper 2.
